Abstract
Disclosed are a polymer electrolyte membrane for fuel cells and a membrane electrode assembly and fuel cell including the same. The polymer electrolyte membrane includes a fluorine-based cation exchange resin having proton conductivity and fibrous nanoparticles having a hydrophilic group. By using the fluorine-based cation exchange resin having proton conductivity and the fibrous nanoparticles having a hydrophilic group in combination, performance of a fuel cell including the polymer electrolyte membrane is not deteriorated and the polymer electrolyte membrane prevents gases from permeating thereinto and has enhanced durability for extended use. A fuel cell including the above-described polymer electrolyte membrane is provided.
